Rosie Emerges After Yearlong, 6,240-foot Journey

November 29, 2018

Rosie, a massive 30-foot wide and 300-foot long tunnel boring machine, emerged in the fall of 2018 after a yearlong, 6,240-foot journey under downtown Akron, Ohio. This gigantic tunnel boring machine began building the 27-ft diameter Ohio Canal Interceptor Tunnel in August 2017.

The tunnel begins at Hickory Street in the Cascade Valley area and will end at W. Exchange Street near downtown Akron. Once complete, the underground tunnel will prevent sewage from reaching local waterways, storing 26-million gallons of combined sewer overflow, averaging 467 million gallons in an average year.
